From the onset of purchase of a 2013 toyota sienna xle, the air conditioner has emitted a foul odor that smells like mold. nor will the a/c system adequately cool the vehicle until being driven sometimes as long as ten miles, if then. we have been told to turn off the a/c before arriving home to eliminate the odor and given a toyota print out that this is a known problem that is specific to the 2013 toyota sienna. on the last scheduled maintenance freon was added but did not eliminate the odor or improved the a/c output. the foul odor never goes away while driving and may be an environmental hazard for persons with a lung or breathing condition. this is a totally unacceptable solution for the risk of being exposed to a potential dangerous and unknown noxious fume to the owner of the vehicle. *tr
